The GRIA project set out to make the Grid usable by industry. The

The U.K. National Crystallography Service (NCS) has developed a prototype e-science infrastructure for the provision of a small molecule crystallography service from sample receipt to results dissemination. This paper outlines the two strands of this service, which (a) enable a user to contribute in the conduction of an experiment and (b) provide an effective route for the archival and dissemination of the arising results. Access to use the NCS facilities and expertise and a mechanism to submit samples is granted through a secure Grid infrastructure, which seamlessly provides instantaneous feedback and the ability to remotely monitor and guide diffraction experiments and stage the diffraction data to a securely accessible location. Publication of all the data and results generated during the course of the experiment, from processed data to analyzed structures, is then enabled by means of an open access data repository. The repository publishes its content through established digital libraries' protocols, which enable harvester and aggregator services to make the data searchable and accessible.

Service Level Agreements (SLA) include quality of service (QoS) constraints and bounds that have to be honoured by the service provider. To maximise the Service Provider revenue while satisfying the QoS requirements of the agreed SLAs it is important to be able to perform a dynamic distribution of the service provider resources between the services and SLAs. This distribution should be based on the current status and predicted evolution of the QoS characteristics. This paper describes the experiences managing SLA obligations from a service provider perspective in a scenario where dynamic deployment of services can be undertaken. The main issues faced to deal with the management of SLAs in this context are detailed. The adopted solution, based on GRIA (a Service Oriented Architecture framework) is discussed.

Abstract. A central requirement for achieving the vision of run-time discovery and dynamic composition of services is the provision of appropriate descriptions of the operation of a service, that is, how the service interacts with its environment, be it agents or other services. In this paper, we use experience gained through the development of real-life Grid applications to produce a set of requirements for such descriptions and then attempt to match those requirements against the offerings of existing work, such as OWL-S [1] and IRS-II [2]. Based on this analysis we identify which requirements are not addressed by current research and produce a model for describing the interaction protocol of a service in response. The main contributions of this model are the ability to describe the interactions of multiple parties with respect to a single service, distinguish between interactions initiated by the service itself and interactions that are initiated by clients or other cooperating services, and capture within the description service state changes relevant to interacting parties that are either a result of internal service events or interactions. The aim of the model is not to replace existing work, since it only focuses on the description of the interaction protocol of a service, but to inform the further development of such work.

5G technologies will change the business landscape for mobile network operation. The use of virtualization through SDN, NFV and Cloud computing offer significant savings of CAPEX and OPEX, but they also allow new stakeholders to rent infrastructure capacity and operate mobile networks, including specialized networks supporting so-called vertical applications serving specific business sectors. In the resulting diverse stakeholder communities, the old trust assumptions between network operators will no longer apply. There is a pressing need for a far broader understanding of trust in such networks if they are to operate safely and securely for the engaged stakeholder communities. This paper describes the work carried out in the 5G-ENSURE project to address this need.
